PROTOGALAXY
In physical cosmology, a protogalaxy, also known as a “primeval galaxy,” is a cloud of gas forming into a galaxy. The star formation rate during this period of galactic evolution plays a crucial role in determining whether a galaxy will become a spiral or elliptical galaxy. A slower rate of star formation tends to produce…
